HP ProLiant Power Interface Control Utility 9
Calibrate and display power limits
-c:
This command forces the system go into idle state to get the lowest possible power configuration. Once the
value has been obtained, the system displays the following updated information:
• Maximum Chassis Power Available (AC): the total power supply capacity available in the chassis
• Minimum Chassis Power Achieved (AC): the lowest power achieved in idle state with the current system
configuration
• Power Limits (AC): the Power Control Mode power range that guarantees full operation
For more information, see "Set Power Configuration Mode (on page 9 )."
IMPORTANT: System performance degrades while acquiring Power Profile.
IMPORTANT: When Power Control Configuration Mode is set to User Configurable (3), the
system returns to the default Power Control Configuration Mode (1) after system calibration
completes. The user is responsible for setting a new Power Control Configuration Mode and level.
Set power configuration mode
-s -mmode -lpower:
This command updates the chassis Power Control Configuration Mode. The Power Management Control
table shows the valid values for mode. Power is required when setting Power Control Configuration to User
Configurable.
Mode Configuration
0 No Redundancy
Power throttling disabled.
1 AC Redundancy with throttling (Default mode)
This provides Maximum Performance with PS Redundancy. Power control logic will only throttle the
performance of each node in the case where the total power draw by the chassis attempts to exceed
the power supply capacity. In this mode, the box is expected to survive an unexpected AC Power loss
to one of the power supplies.
2 Full AC/DC Redundancy
Power control logic maintains a power cap value at the DC rating of a single power supply (Example:
460W, 750W, or 1200W), such that if one power supply experiences a DC or AC failure, the
chassis remains on-line and operational. User must be cognizant of the minimum power consumption
of the chassis and this must be less than the rating of a single power supply.
3 User Configurable (Available only with the LO100 Advance Pack, iLO Scale Out, or iLO Advanced
Pack)
User specifies the power envelope for the chassis, within the capabilities of the HW installed. Before
setting this mode, it is required that the user run PPIC's Calibrate and display power limits command
to obtain the minimum and maximum power consumption envelope for the chassis.
HP recommends the following steps to properly define the Power Control Configuration level for User
Configurable (3) mode:
1. Run the target system (all nodes in the chassis) at the production level load.
2. Calibrate the chassis to obtain the power profile and display the information (ppic -c).
